I am Tisza Gergő (eastern name order), a Wikipedian from Hungary (my user page there has more information). I am a volunteer for Wikimedia Hungary and a MediaWiki developer. I'm mainly involved in technical issues (gadgets, bots, bug reports etc.) and governance discussions (via the chapter and via the movement strategy process); sometimes I do work related to copyright law (OTRS, local lobbying) and interface translation. I used to be a content writer and administrator on Hungarian Wikipedia but I don't have time for that these days.
Since 2013 I have been working for the Wikimedia Foundation. My staff account is User:Tgr (WMF). Although I work for the Wikimedia Foundation, contributions under this account are exclusively in my individual, personal capacity.
